The Weathering of Plastics Materials in the Tropics. 6. The Further Evaluation of a Solar Radiation Concentrating Device (EMMA) as a Means of Accelerating the Weathering of Plastics

Abstract

This report is an account of a second trial conducted at Desert Sunshine Exposure Test Inc. using the facility of the EMMA and EMMAQUA machines which are reported to accelerate natural weathering. Low density polyethylene and polyacetal specimens were tested and no real acceleration factors could be found for the EMMA machines over natural 45 deg exposure. (Author)
